Abstract (en)
[origin: EP1296144A2] To provide a magnetic encoder that has an increased detecting sensitivity, can be thin-walled, have an increased reliability and an increased durability, can easily be handled during manufacture and assembly and is excellent in productivity, the magnetic encoder (10) includes a multi-pole magnet element (14) having opposite magnetic poles alternating with each other in a circumferential direction, and a core metal (11) for supporting the multi-pole magnet element (14). The multi-pole magnet element (14) is made of a sintered element prepared by sintering a powdery mixture of a powdery magnetic material and a powdery non-magnetic metallic material. <IMAGE>
